Reporting Issues

It's very useful to get the tree expanded by the Scala compiler, rather than the original source. Adding the -Xprint:typer flag to the Scala compiler will show code like the following:

// println("Hello world")
package $line4 {
  object $read extends scala.AnyRef {
    def <init>(): $line4.$read.type = {
      $read.super.<init>();
      ()
    };
    object $iw extends scala.AnyRef {
      def <init>(): type = {
        $iw.super.<init>();
        ()
      };
      object $iw extends scala.AnyRef {
        def <init>(): type = {
          $iw.super.<init>();
          ()
        };
        private[this] val res1: Unit = scala.this.Predef.println("Hello world");
        <stable> <accessor> def res1: Unit = $iw.this.res1
      }
    }
  }
}

Adding the generated code to an issue is very useful for debugging.
